vue 实现边输入边搜索功能的实例讲解

<template>
 <div id="search">
 <input type="text" class="search" placeholder="搜索" v-model.trim="title" />
 </div>
</template>

<script>
// 节流函数
const delay = (function() {
 let timer = 0;
 return function(callback, ms) {
 clearTimeout(timer);
 timer = setTimeout(callback, ms);
 };
})();
export default {
 name: 'search',
 data() {
 return {
  title: '',
  search:[]
 };
 },
 watch: {
 //watch title change
 title() {
  delay(() => {
  this.fetchData();
  }, 300);
 },
 },
 methods: {
 async fetchData(val) {
  const res = await this.fetch({
  url: '写上你的URL',
  method: 'GET',
  params: { title: this.title },
  });
  this.search = res.data.list;
 },
 },
 mounted() {},
};
</script>
